    Application of Laubscher MRMR classification system in the design of open-pit chromite mines – A case study
    (World Researchers Associations, 2025) Dinesh, K.; Akhil, A.; Kunal, M.; Kumar, K.A.
    The study work was conducted at the Boula Chromite Mine site, focusing on geotechnical field observations in and around the area. The investigation aimed to comprehensively analyze surface and underground conditions, structural features, rock mass conditions and slope stability. The stereo net plot method was employed for slope stability analysis. Slope failures in rock masses were observed at the mine site at few locations, prompting us to delve into understanding the events and proposing precise recommendations for safe and efficient mining practices. The analysis of results formed the core objective of this study. To achieve the stated goal, a rational and systematic study in the field was conducted. This encompassed examining the geological and structural setup of rock formations, conducting field investigations to asses various geotechnical parameters, identifying the most influential factors affecting rock mass behavior, categorizing rock masses into groups based on similar behavior (rock mass classes), gathering structural data on slopes, classifying rock mass conditions using Laubscher’s rock mass classification and determining failure modes (planar, wedge, toppling and circular) in rock slopes through graphical analysis. The comprehensive rock mass classification and failure analysis were compiled in this work. The findings are crucial for identifying and thoroughly analyzing potential risks. This knowledge can play a pivotal role in ensuring the safety and efficiency of mining operations in and around the Boula Chromite Mine site. Moreover, the knowledge acquired from the study can be instrumental in planning and opening pit projects with similar geotechnical and mining conditions. The study thus provides valuable information for the broader field and contributes to the overall advancement of safe and effective mining practices. © 2025, World Researchers Associations.
